Parornix alpicola (Wocke, 1877)
The larva first makes a lower-surfsce epidermal corridor. Next the larva begins to feed on the sponge parenchyma, subsequently also the palissade parenchyma; the initial corridor becomes obliterated. The final mine is full depth, occupies half of a leaf, at one side of the midrib, and is almost flat. The upper side turns orange brown. Finally the larva vacates its mine and spins a new leaf into a pod, that is eaten from the inside. If needed still another leaf is treated the same way. Pupation in a brownish cocoon onder a folded leaf margin.
Univoltine; full-fed (no longer mining) larvae in late July – early August (Emmet ao, 1985a).
